3. Product Description: A pipe support with “strut” used to support roof-mounted electrical conduit, solar piping, gas pipes, and othermechanical piping. Unique design absorbs thermal expansion and contraction of pipes thus preventing damage to the roof mem-brane. Pipes rest on a strut system which is made of hot-dip galvanized steel. The pipe support base is made of polycarbonateresin, and all other metal parts are made of hot-dip galvanized or stainless steel. Pipestand will accommodate up to 2.5 pipe (insidediameter) or up to 3" outside diameter pipes.

4. Product Performance: This strut and shape of the supporting base serve to keep the pipestand roller system directly beneath thepipe without binding and allows for some lateral expansion of the piping system. The base is gently rounded to allow movementupon the roof to prevent gouging the roof membrane. Clearance above the roof for the 2.5-Conduit Support-2 is 2.5 inches, the 2.5-Conduit Support-5 is adjustable from 3.25 inches to 5 inches. Clearance for the 2.5-Conduit Support-7 is adjustable from 3.25 to7.50 inches. Clearance for the 2.5-Conduit Support-12 is adjustable from 5.5 to 12 inches. More than one conduit or pipe may beganged on the pipe support and attached with typical pipe clamps or clips so long as the total load weight per support does notexceed 100 pounds.

5. Compatibility: Pillow Block Pipestands are recommended for use on and are compatible with all current types of decking and withall commonly used built-up and single-ply roofing membranes where roof-mounted pipes occur.

6. Load Weight: Maximum load weight may not to exceed 100 lbs. per pipestand.

7. Composition and Materials: The pipestand consists of two major components: (1) A one-piece polycarbonate roof deck basehousing and, for the 2.5-Conduit Support, 3/8" diameter all thread are connected to the base to adjust the height of the strut, and (2)a 12" by 5/8" by 13/16" hot-dip galvanized strut to support the attached conduit or pipe. Carbon black is added to the polycarbonateresin for UV resistance and protection.

8. Size: The deck base is 7.50" by 10" or the 2.5-CS-12 is 9" by 15.25" and the strut is 1-5/8" by 13/16" and 12 inches long. 2.5-Conduit Support has a maximum pipe clearance of 2.5", 5", 7" and 12" from bottom of pipe support.

9. Installation: (1) Center the pipestand beneath the pipe so that the strut allows the pipe to be squarely over the pipestand. (2) Adjustthe pipestand to the desired height and even load with other pipestands. Make certain the strut is level. (3) Set the pipe in thepipestand without dropping or causing undue impact. An additional sheet of roofing material, a traffic pad, or a MIRO Deck Plateshould be installed beneath the pipestand. For built-up roofs, all loose aggregate from an area 15" square should be removed fromthe area directly beneath the pipestand and then follow the installation directions set forth above. Care should be taken to installeach pipestand so it supports a proportional and equal amount of weight at each pipestand.

OPTIONAL METHOD OF INSTALLATION (Not recommended): Where code requires or as desired, the pipestands may be at-tached to the roof by appropriate and compatible rooftop fasteners.

10. Spacing: Manufacturer’s recommended spacing is not to exceed 10 foot centers depending upon the load. Do not exceed 100 lbs.load weight and make certain each pipestand is adjusted in height to even load.

11. Availability: Pillow Block pipestands are marketed throughout the United States through representatives and distributors.

12. Maintenance: Normally maintenance is not required. Semi-annual inspection is required to check pipestand position and set pipealignment, weight distribution and improper installation which may cause pipestand damage or failure.

Specification and Data SheetModel Nos. 12, 16 and 20 Base Strut-7

Model Nos. 16 and 20 Base Strut-12(Numbers 12, 16 and 20 designate length of strut on support)

1. Product Name: PILLOW BLOCK PIPESTAND MODELS 12, 16 and 20-Base Strut.


3. Product Description: A pipestand with a strut and clamp pipe support system used for ganging roof mounted gas pipes, electricalconduit, solar piping and other mechanical piping. Unique design absorbs thermal expansion and contraction of pipes thus preventingdamage to the roof membrane. Pipes rest on a 12"or 16" length of strut which is mounted on the base. The pipes can then be fastenedby using typical clamps locked to the strut. The pipe support base is made of stainless steel, hot-dip galvanized steel, or polycarbonateresin; and the strut and hardware are made out of hot-dip galvanized or stainless steel.

4. Product Performance: As daytime temperatures warm the roof membrane and the mechanical pipe network found on the roof, the pipenetwork expands and moves over the roof. When the roofing membrane and pipe network cools, the process is reversed. With adifference of 20 degrees F. between nighttime and daytime temperatures, 100 ft. of 1" steel pipe may move as much as .25 inches perday. The base to which the strut and supported pipe are affixed is gently rounded to allow movement upon the roof to prevent gougingthe roof membrane. The base strut allows for movement without damaging the roof membrane.

5. Compatibility: Pillow Block Pipestands are recommended for use on and are compatible with all current types of decking and with allcommonly used built-up and single-ply roofing membranes where roof-mounted pipes occur.

6. Load Weight: Maximum load weight not to exceed 150 lbs. per steel pipestand, and 125 lbs. per 16-Base Strut-7 and 16-Base Strut-12 and 250 lbs. per 20-Base Strut-7 and 20-Base Strut-12.

7. Composition and Materials: The pipestand consists of two major components: (1) A one-piece stainless steel, hot-dip galvanized steelor polycarbonate resin support base, and (2) a single or double 12", 16" or 20" piece of galvanized, steel, strut connected with stainlesssteel 1/2" or 3/8" diameter all thread to each base. Carbon black is added to the polycarbonate resin for UV resistance and protection.

8. Size: The Pillow Block Pipestand Base Strut Models (Adjustable Height) are made as follows:

Polycarbonate:16-Base Strut-7: The deck base is 9" by 15.25", has a maximum bar length of 16", and can adjust in height from a low of 4" to a highof 7.5" in elevation above the roof membrane. The 16-Base Strut-12" has a deck base of 9" by 15.25" and is adjustable up to 12".20-Base Strut-7: The deck base is 16" by 18", has a maximum bar length of 20", and can adjust in height from a low of 4.5" to a highof 7.5" in elevation from bottom of pipe support. The 20-Base Strut-12" has a deck base of 16" by 18" and is adjustable up to 12".Steel:12-Base Strut-7: The deck base is 12" by 16" , has a maximum bar length of 12", and can adjust in height from a low of 3.5" to ahigh of 7.5" in elevation from bottom of pipe support.16-Base Strut-7: The deck base is 12" by 16" , has a maximum bar length of 16", and can adjust in height from a low of 3.5" to ahigh of 7.5" in elevation from bottom of pipe support.

9. Installation: (1) Center the pipestand beneath the pipe so that the strut is squarely over or under all lines of pipe. If more than one pipeis being supported, adjust for even distribution of weight. (2) Adjust the pipestand to the desired height and even load with otherpipestands. Make certain the strut bar is level. (3) Set the pipe in the pipestand without dropping or causing undue impact. If desired, anadditional sheet of roofing material, a traffic pad, or a MIRO Deck Plate can be installed beneath the pipestand. For built up roofs, allloose aggregate from an area 20" square should be removed from the area directly beneath the pipestand and then follow the installa-tion directions set forth above. Care should be taken to install each pipestand so it supports a proportional and equal amount of weight.

OPTIONAL METHOD OF INSTALLATION (Not Recommended): Where code requires or as desired, the pipestands may be attached tothe roof by appropriate and compatible rooftop fasteners through holes then drilled in the bottom of the pipestand pitchpan at the time ofinstallation.

10. Spacing: Manufacturer’s recommended spacing should not exceed 10 foot centers depending upon the load. Do not exceed loadweights designated above and make certain each pipestand is adjusted to even load at each pipestand throughout the roof system.

11. Availability: Pillow Block Pipestands are marketed throughout the United States through representatives and distributors.

Themaximum outside dimension of the pipe or conduit the Model 4-R will hold is 5" diameter.


3. Product Description: A “roller-bearing” pipe support used to support roof-mounted gas pipes, electrical conduit, solar piping and othermechanical piping. Unique design absorbs thermal expansion and contraction of pipes thus preventing damage to the roof membrane.Pipes rest on a self-lubricating roller system which is made of a polycarbonate resin rod and a sturdy polycarbonate resin roller. The pipesupport base and roller rod are made of polycarbonate resin, and all metal parts are made of stainless steel. Pipestand will accommo-date up to 4" inside diameter pipe or up to 5" outside diameter pipes.

4. Product Performance: As daytime temperatures warm the roof membrane and the mechanical pipe network found on the roof, causingthem to expand, the roller bearing in the pipestand rolls beneath the pipe it supports. This reduces or eliminates the friction that wouldotherwise occur between the pipe and the roof membrane. When the roofing membrane and pipe network cools, the process is re-versed, and the pipes roll back on the roller bearing as they contract. With a difference of 20 degrees F. between nighttime and daytimetemperatures, 100 ft. of 1" steel pipe may move as much as .25 inches per day. The “U” shaped roller serves to keep the pipestand rollersystem directly beneath the pipe without binding and allows for some lateral expansion of the piping system. The base is gently roundedto prevent gouging the roof membrane.

5. Compatibility: Pillow Block Pipestands are recommended for use on and are compatible with all current types of decking and with allcommonly used built-up and single-ply roofing membranes where roof-mounted pipes occur.

Specification and Data SheetMODEL NO. 6-RAH-RS (SS or HDG)

1. Product Name: MODEL NO. 6-RAH Restraint Support corresponds to the largest pipe this support will hold. Pipe that is called 6" has an insidediameter of 6" and an outside diameter of 8.5".


3. Product Performance: Products were designed to restrain piping where codes require. This system is designed for pipe carrying water, steam, or gas.

4. Product Description: Support frame is designed for a maximum of 6" diameter schedule 40 (std. weight) carbon steel pipes with MIRO Industriessupports (sleepers) as a maximum of 10'-0" o/c and restraint frames at a maximum of 40'-0" o/c.

5. Compatibility: MIRO Supports are recommended and are compatible for use with all current types of decking and with all commonly used buildupand single-ply roofing membranes where roof-mounted pipes occur.

6. Load Weight: Weight load should be evenly distributed, on both restraint support and non-penetrating supports.

7. Composition and Materials: Each support consists of three components: A steel frame which includes a plate for the rooftop and bracket for underthe roofing substructure, typical pipe clamps, and two sided Eternabond tape.

8. Size: 6-RAH-RS is suited to carry all 6" piping and smaller. The deck base size is 12" by 16" and has a maximum cradle width of 8.5". The 6-RAH-RS can adjust in height from a low of 2" to a high of 7" on 1/2" all thread from bottom of pipe support. For units requiring a 12" in height, pleasecontact MIRO Industries.

9. Installation: To install the support frame: (1) Align the support over structural steel or (attachment locations should be approved by engineer). Usebolts to fasten frame to structural steel. (2) Fasten typical pipe clamps to pipe (fasten to pipe per manufacturer recommendations). (3) Place Ashlandbutyl tape down on rooftop material and adhere to base.

Miro will not be responsible for installation or workmanship or roof penetrations.

10. Spacing:A. It is recommended that a structural analysis of the restraint support(s) based upon proposed project layouts be performed to accurately deter-

mine the code level site-specific frame reactions. This will generally significantly reduce the magnitude of frame loads to the supporting struc-ture, and minimize the need for reinforcement or additional framing.

B. Maximum restraint support spacing indicated are based upon support capacity, and not upon the supported component capacity. Supportspacing must be determined by the specifier to meet the requirements of the supported component code standard maximum longitudinal andlateral supports spacings.

C. The capacity of the supporting structure and method of restraint support attachment (i.e.: bolting) must be verified by the structural engineer ofrecord. Additional structural framing and/or local reinforcement may be required in order to support the restraint frame base reactions.

Product Performance: The roller or clevis hanger system serves to keep the pipestand hanger system directly over and beneath the pipewithout binding and allows for some lateral expansion of the piping system. The base is gently rounded to prevent gouging the roofmembrane. Drainage ports are provided in the metal bases to prevent ponding within the device.

6. Compatibility: Pillow Block Pipestands are recommended for use on and compatible with all current types of decking and with all com-monly used built-up and single-ply roofing membranes where roof-mounted pipes occur. With heavier loads it is prudent to use a MIROsupport pad or traffic pad to further protect the roof membrane.

7. Load Weight: Maximum load weight not to exceed 1,600 lbs. per pipestand or 800 lbs. on each base.

8. Composition and Materials: The pipestand consists of three major components: (1) Two roof deck bases made of 11-gauge stainless orhot-dip galvanized steel or sturdy polycarbonate bases which set upon the roof membrane, (2) A braced strut assembly of 3" square strutmade of 11-gauge hot-dip galvanized steel which is supported by, rests upon, and is connected to the two or four bases, and (3) a hangersystem supported by the strut consisting of a stainless steel all-thread supporting rod which suspends a clevis hanger or a steel or polycar-bonate resin roller system all suspended from the strut assembly.

9. Size: The Pillow Block Pipestand Model 16-H is made as follows: Each of the two deck bases is 20" by 20" (Stainless Steel or Hot-dipGalvanized), or 39" by 16" (Polycarbonate), has a cradle width which allows a minimum of 24" between the strut assembly, and can be builtto adjust in height to support pipe from a low of 2 inches to a desired custom height. The strut is 3" square, the strut assembly is constructedat various heights to give pipe clearance adjustment above the roof.

10. Adjustable Height: The model 16-H and its related configurations allow adjustable height as desired or required by the code or roof system.Each model can be configured to allow plus or minus height above the roof. Cross-bracing two pipestands every 4th or 5th pipestand isrecommended and required for elevations 24" and higher. Purchasers should specify desired heights upon ordering the pillowblock hangers.

11. Installation Process: (1) Center the pipestand beneath the pipe so that the cradle allows the pipe to be squarely over and through the rolleror clevis hanger of the pipestand. (2) Adjust the pipestand to the desired height and to even load with other pipestands. Make certain thehorizontal support strut is level. (3) Set the pipe in the clevis hanger without dropping or causing undue impact. For heavier loads, it isprudent to install an additional sheet of roofing material, a MIRO Deck Plate or MIRO Support Pad beneath the pipestand. For built up roofs,all loose aggregate from an area 24" square should be removed from the area directly beneath the pipestand and then follow the installationdirections set forth above. Care should be taken to install each pipestand so it supports a proportional and equal amount of weight at eachpipestand.

OPTIONAL METHOD OF INSTALLATION (Not Recommended): Where code requires or as desired, the pipestands may be attached to theroof structure by appropriate and compatible rooftop fasteners through holes then drilled in the bases.

12. Spacing: Manufacturer’s recommended spacing is not to exceed 10 foot centers depending upon the load. Do not exceed 1,600 lbs. loadweight (800 lbs. on each base) and make certain each pipestand is adjusted in height to even load at all pipestands.

INSTALLATION OF MODELS6-H, 8-H, AND 16-H

1. Hanger or trapeze structure is shipped assembledwith two or more leg supports, one top support, twoor more gusset flanges with hardware, and the all-thread support with nuts and washers.

2. The bases are not attached to the hanger systemfor convenience and ease of shipping, and areshipped with nuts, washers, and bolts for each base.

3. Insert the legs of the hanger structure into both basesand tighten all bolts provided so bolts and gussetstructure are tight on hanger legs. Required torqueis 8 foot pounds. Eight pounds of torque should beapplied to each bolt for correct tightness.

4. Clear all gravel and aggregate away from wherebase plates are to be positioned upon the roofmembrane.

5. Install a MIRO Support Pad or an appropriate roofpad upon roof membrane. Pad must be compatiblewith the roof system. Comply with all MIRO and roofmanufacturer loading and other requirements.

6. Position bases on pad.

7. Make sure to adjust all-thread fastened to the hangerin order to create positive and equal load on eachsupport.

8. After installation is complete, check all bases to seethat all rest upon the roof. Reinspect again threemonths later and every six months thereafter.

INSTALLATION AND MAINTENANCE

TYPICAL INSTALLATION:(1) Center the pipestand beneath the pipe so that the cradle allows the pipe to be squarely over and through

the roller of the pipestand. (2) Adjust the pipestand to the desired height and even load with other pipestands.Make certain the strut or roller is level. (3) Set the pipe in the pipestand without dropping or causing undueimpact. If desired, an additional sheet of roofing material, a traffic pad, or a MIRO Deck Plate can be installedbeneath the pipestand. For built-up roofs, all loose aggregate from an area 15" square should be removed fromthe area directly beneath the pipestand and then follow the installation directions set forth above. Care shouldbe taken to install each pipestand so it supports a proportional and equal amount of weight at each pipestand.

OPTIONAL METHOD OF INSTALLATION (Not recommended): Where code requires or as desired, thepipestands may be attached to the roof by appropriate and compatible rooftop fasteners through holes thendrilled in the bottom of the pipestand pitchpan at the time of installation.

MAINTENANCE:Normally maintenance is not required. Semi-annual inspection is required to check pipestand position and

set pipe alignment, weight distribution and improper installation which may cause pipestand damage or failure.

SPECIAL INSPECTION AND MAINTENANCE FOLLOWING INSTALLATION:MIRO has found that contractors may not properly install the pipe supports.Because of the necessity to check installation methods of contractors and because of the dynamic move-

ment of pipes on the roof, installation inspection following job site installation is a critical factor in the successof supporting pipe and protecting the roof membrane. Movement of pipe on the roof, especially heavier pipe,as the pipe settles into its final operating position may result in significant changes in position, requiring someadjustment following installation with built in forces and leverage requiring significant movement.

Therefore, following installation the following inspection should take place:

1. Determine that the pipe is still resting in a position centered over the pipestand base, centered between thetwo bases, or centered properly in the pipestand cradle, rollers, or clevis hanger.

2. Determine that the pipe is running at a perpendicular angle to the cradle, roller, or the pipe base housing orsystem.

3. Determine that the base is still resting upon a traffic pad, support pad, or deck plate.

4. Determine that each support is resting flat upon the roof and not angled in any manner. For example, alateral force on the pipestand as pipe settles into its final resting position may cause enough force to pushthe pipestand base upon a side or corner, which is an improper functioning position and could damage theroof.

5. Determine that the pipestand system and each pipestand is functioning properly. Determine if any otherreason or foreign object may be impeding the proper function of the pipestand system and each individualpipe support.

Re: Metallurgical Opinion

Dear Mr. Neider:

You have requested an opinion regarding your use of stainless steel and hot-dip galvanized steel on rooftops underconditions where such metal is exposed to weather conditions including wide temperature changes, rain, snow, salt,humidity, and salt humidity.

This letter contains my research and opinion regarding the issues as I have set forth herein and assumptions maderegarding the conditions and use of your steel products. Specifically, you have requested an opinion, which is basedupon the following facts and assumptions.

1. Your products are made of 304 stainless steel ASTM A666, including flat surfaces, all threads, nuts, washers,and smooth rods.

2. Your products are made of hot-dip galvanized steel ASTM A123, including 16 gauge and thicker material.3. Weather conditions will consist of temperatures ranging from -45F to a high of 115F with accompanying roof top

temperatures which may vary according to circumstances upon the roof to as much as 200F.4. Weather conditions, which include intense rain, hot direct sunlight, snow, sleet, intense wind, humidity salt air

humidity, and blowing water, which may contain salt water.5. You have stated you guarantee your products for the life of the roof membrane, which, in some cases, may be

as long as 25 years.

You have also requested an opinion regarding other activities on the roof which include what kind of supervening eventsmay degrade the metal such as (1) metal filing or other pieces of metal in contact with or resting upon the metal surfaceof the metal products, (2) scraping or mechanically damaging the surface of metal products, or (3) damage fromenvironmental sources other than weather.

My conclusions are as follows:

1. It is my opinion that if you use stainless steel (ASTM A666) and hot-dip galvanized steel (ASTM A123) undernormal conditions, you can expect the metal features of your products to function upon the roof for at least 25years with no degradation, no loss of function or operation.

2. It is my opinion that wile hot-dip galvanized parts will perform adequately for normal conditions, parts that aremechanically damaged by scraping or scratching the surface to the point that the zinc coating is removed orreduced significantly in thickness will deteriorate over time. If damage does occur, the resulting rust can beremoved and the area painted with a zinc dust based paint.

3. It is my opinion that a salt air humidity, which is found along the seacoast or in a damp heavy industrialarea, can over time cause deterioration of the galvanized coating. This is due to the presence of chloridesin both the salt water and some industrial environments. The chlorides are able to react with the zinccoating to form an oxide coating. The oxide which is formed does not impair the usefulness of the partuntil such time as the zinc is completely removed and the base metal has oxidized. If the product is to beused in a heavy industrial area with unknown pollutants present, the 304 stainless steel should be used.

4. It is my opinion that galvanic action will not cause deterioration of the galvanized product. If bare ferrousmaterial is placed in contact with the galvanized material of the products, the bare metal will showincreased oxidation due to galvanic attack.

5. It is my opinion that in the case of 304 stainless steel (ASTM A666), particles on the pipe stands,weather conditions, scraping or scratching will not reduce the life expectancy or the performance orsuch material in your pipe stands for roof top support and the conditions existing there.

6. It is my opinion that the direct sunlight will be reflected rather than absorbed. Galvanized parts reflectninety percent of the sunlight reaching them as do stainless steel. This mean that very little heat will beabsorbed which could damage the roof membrane. If there are any concerns about temperature, a roofpad or traffic pad under the metal support will relieve any concern about heat pick up.

Very truly yours,

James F. HamiltonMetallurgical Engineer

2. Design Emphasis: The 4-DSA duct support has been designed specifically for square and round duct work. The versatility of the designfor this product enables it to expand vertically and horizontally to hold small duct and cable trays running along the roof for maximumefficiency and cost savings to customers, contractors, and owners.


4. Product Description: A frame constructed of strut and MIRO’s patented bases are used to support duct on flat roofs. Unique designallows a sturdy support without penetrating or causing damage to the roof membrane. Ducts rest on a pre-galvanixed gauge channeland are adjustable in height and width. All 4-DSA models are manufactured in a 16 or 14 gauge pre-galvanized telescoping design formaximum adjustability in length and height. The bases are made out of polycarbonate plastic.

5. Product Performance: The frame system serves to keep the duct system directly over and beneath the frame without binding andallows for some lateral expansion of the duct system. The base is gently rounded to prevent gouging.

6. Compatibility: MIRO Duct Supports are recommended for use on and compatible with all current types of decking and with all com-monly used built-up and single-ply roofing membranes where room-mounted ducts occur. With heavier loads it is prudent to use a MIROSupport Pad or other traffic pad to further protect the roof membrane.

7. Load Weight: 4-DSA 12 x 12: Maximum load weight not to exceed 50 lbs. per duct support or 25 lbs. on each base or 10" spiral duct4-DSA 18 x 18: Maximum load weight not to exceed 100 lbs. per duct support or 50 lbs. on each base or 16" spiral duct

8. Composition and Materials: The pipestand consists of two major components: (1) Two roof deck bases of polycarbonate plastic whichset upon the roof membrane, (2) Telescoping assembly which is supported by, rests upon, and is connected to the two bases.

9. Size: Both 4-DSA models have two deck bases 8" x 8". The 4-DSA 12 x 12 has 16 gauge telescoping and has a maximum 12" heightand width. The 4-DSA 18 x 18 has 14 gauge telescoping and has a maximum 18" height and width.

10. Installation Process: (1) Center the duct support beneath the duct so that the frame allows the duct to be squarely over and through thehorizontal bar. (2) Adjust the duct support to the desired height and to even load with other duct supports. Make certain the horizontalsupport strut is level. (3) Set the duct in the horizontal bar without dropping or causing undue impact. For heavier loads it is prudent toinstall an additional sheet of roofing material, a MIRO Deck Plate, or MIRO Support Pad beneath the duct support. For built-up roofs, allloose aggregate from an area 2" larger than each base should be removed from the area directly beneath the duct support and thenfollow the installation directions set forth above. Care should be taken to install each duct support so it supports a proportional and equalamount of weight at each duct support.

OPTIONAL METHOD OF INSTALLATION (Not Recommended): Where code requires or as desired, the duct supports may be attachedto the roof structure by appropriate and compatible rooftop fasteners through holes then drilled in the bases’ pitchpan at the time ofinstallation. After attachment has been made to the roof, the pitchpan may be filled with asphalt material or cement to help seal the areasaround the fasteners.

11. Spacing: Manufacturer’s recommended spacing is not to exceed 8 foot centers depending upon the load. Do not exceed load weightand make certain each duct support is adjusted in height to even load at all duct supports.

12. Availability: Duct Supports are marketed throughout the United States through representatives and distributors.

13. Maintenance: Normally maintenance is not required. Semi-annual inspection is required to check duct support position and set ductalignment, weight distribution and improper installation which may cause duct support damage or failure.

1. Product Name: MIRO HD AND LD MECHANICAL UNIT SUPPORTS


3. Product Description: MIRO Mechanical Unit Supports are supports to elevate rooftop mechanical units such as airconditioning or other devices. The Mechanical Unit Supports are designed so that the mechanical units rest in heavy-dutygrate plank system supports which are connected to bases designed with MIRO technology to protect the roof membrane.The Mechanical Unit Supports are adjustable in that the strut or all-thread can be selected to the appropriate height tolevel the rooftop units. All metal pieces are made out of hot-dip galvanized steel or stainless steel for outdoor weatheringprotection. The MIRO Mechanical Unit Support consists of (1) a MIRO designed base with gently curved edges to protectthe roof membrane and to distribute the weight over the maximum roof surface, (2) hot-dip galvanized steel strut, and (3)hot-dip galvanized plank that fits the supported mechanical unit.

4. Product Performance: MIRO Mechanical Unit Supports can be used to support mechanical devices which are set uponthe roof, and MIRO recommends that such devices not be attached to the roof membrane or the roof structure, but floatfreely upon the roof. As units operate and as daytime temperatures warm and cool, the roof environment and the me-chanical pipe network upon the roof to which a mechanical device may be connected expands and contracts with thetemperature changes. The MIRO Mechanical Unit Supports are designed to support such devices and absorb suchmovement in a way that protects the roof. Vibration eliminators can be added to units if necessary.

5. Compatibility: The Mechanical Unit Support is recommended for use on and is compatible with all current types ofdecking and with all commonly used built-up and single-ply roofing membranes where roof-mounted pipes and devicesare installed.

6. Load Weight: Maximum load weight is equivalent to and is part of the maximum roof top bearing load which MIRO hasdesigned for its bases. MIRO recommends such loading not exceed 2.5 lbs per square inch.

7. Composition and Materials: The Mechanical Unit Support is made of hot-dip galvanized steel or can be made of stain-less steel or polycarbonate.

8. Size: The Mechanical Unit Support is manufactured to adjust in height to the specifications and dimensions required byeach roof top application. Light duty unit sizes include 18" by 18", 24" by 24", 24" by 30", 30" by 30" and 36" by 36".Custom units can be provided.

9. Installation: (1) Determine the dimension and location of the supported unit upon the roof and the desired height, (2) placethe Mechanical Unit Supports in the approximate positions so as to allow the mechanical unit or device to fit down in andupon the side support, (3) take final measurements and adjust the Mechanical Unit Support to fit properly allowing an evenload to be distributed throughout the grading system to ensure that an even amount of load is placed upon each leg and basesupport, (4) adjustment in height can be obtained by moving the framing system up and down the leg of the support byadjusting the brackets. Care should be taken to adjust each Mechanical Unit Support to make sure equal weight and load isresting upon each leg and that no support carries more weight than two pounds per square inch.

10. Spacing: The Mechanical Unit Support should be spaced at intervals so as to allow proper installation of the mechanicalunits or devices and so as not to exceed recommended weight bearing upon rooftop materials which MIRO recommendsnot exceed two pounds per square inch.

11. Availability: Mechanical Unit Supports are marketed throughout the United States through representatives and distribu-tors.

12. Maintenance: Normally maintenance is not required. Semi-annual inspection is required to check support position, pipealignment, weight distribution, and improper installation which may cause system failure or damage.

Specification and Data SheetMODELS DP-12, DP-18 and DP-24

1. Product Name: MIRO DECK PLATE MODELS DP-12, DP-18 and DP-24


3. Product Description: A rigid plate which supports other mechanical devices, pedestals or pipe supports by providing a flatsmooth surface upon which supporting devices may rest to protect roof-top membranes and to further distribute roof top weightto protect submembrane insulation and decking material. The design of the deck plate allows rooftop pipe supports, pedestalsand other supporting devices to be installed without penetrating the roof membrane and further allows the daily movement of apiping system to properly carry the load being borne by the supporting devices as thermal expansion and contraction moves theroof system of pipes or devices supported by the deck plate. The deck plate is made of 16, 18 or 20 gauge stainless or hot-dipgalvanized steel plate which prevents rusting, enhances the longevity of the roof, and provides maximum operational efficiencyfor other rooftop pipestands, pedestals and support devices.

4. Product Performance: As daytime temperatures warm the roof membrane and the roof environment, the mechanical pipenetwork found on the roof and other mechanical devices located thereon expand. As temperature cools, the process reverses.This movement of the rooftop piping system and other devices causes friction upon such supporting devices, the roof membraneand the insulation and decking material below the roof membrane. The MIRO deck plate provides a smooth surface for suchsupporting devices to further absorb the friction of the rooftop movement and distributes the weight of the piping and pipe supportover a larger area of the roof. The result is that roof membrane material is not pushed or pulled, does not adhere to the support-ing pipestand or device, and when properly installed the Deck Plate prevents the insulation or deck material beneath the roofmembrane from being damaged or crushed.

5. Compatibility: The deck plate is recommended for use on and is compatible with all current types of decking and with allcommonly used built-up and single-ply roofing membranes where roof-mounted pipes and devices are installed.

6. Spacing: Maximum load weight not to exceed 200 pounds per plate for the 12" by 12" size, 400 pounds per plate for the 18" by18" size, and 800 pounds per plate for the 24" x 24" size, nor should the load weight be confined to unusually small areas of thedeck plate.

7. Composition and Materials: The deck plate is made of 18 gauge stainless steel and is gently curved at the edges to preventgouging or ripping of the roof membrane.

8. Size: The MIRO deck plate is manufactured in 12" x 12", 18" x 18" and 24" x 24" sizes, or custom if needed.

9. Installation: (1) Determine the spacing for the pedestals, pipe supports or other rooftop devices and center the deck plate at thecenter point requiring support. (2) Install the mechanical unit or pipe support as required by the manufacturer specifications andinstallation requirements. (3) Set the pipe in the pipe support or other supporting device without dropping or causing undueimpact. If desired, the installation of an additional sheet of roofing material or traffic pad beneath the deck plate can be installed.For built-up roofs, all loose aggregate from an area 2" beyond the edge of each deck plate should be removed from the areadirectly beneath the plate and then follow the installation directions set forth above. Care should be taken to install each deckplate, pedestal, pipe support or other device so as to support a proportional and equal amount of weight. MIRO suggests that theplate and other supporting device upon it be installed unattached to allow the supporting device to move in the small incrementsrequired as expansion and contraction of the piping system occurs each day.

10. Spacing: The deck plate should be set upon the roof at spacing centers as recommended by the manufacturer’s specificationsfor the supporting device which is to rest upon the deck plate.

11. Availability: Deck plates are marketed throughout the United States through representatives and distributors.

12. Maintenance: Normally maintenance is not required. Semi-annual inspection is required to check deck plate position and pipealignment, weight distribution and improper installation which may cause system failure or damage.
